       Title     : TCP MD5 Signature Option

This memo describes a TCP extension to enhance security for selected TCP 
applications.  It defines a new TCP option for carrying an MD5 digest in a 
TCP segment.  This digest acts like a signature for that segment, 
incorporating information known only to the connection end points.  Using 
this option in the way described in this paper significantly reduces the 
danger from security attacks on critical TCP applications on the Internet.
 
This document specifies an experimental protocol for use in the Internet.

Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-heffernan-tcp-md5-02.txt".

NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.



Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
